Okay. So in the ideal case only one of these backends is compiled in, but the list can get long. I'm asking because David and I currently port another caam-like mechanism to the most recent kernel which will also hook in there. Out driver adds trusted keys support (with caam alike blobs) for i.mx SoCs that come with DCP instead of CAAM. Patches will hopefully materialize soon. -- Thanks, //richard
